Shake or Vibration Issues

Wrench589 · March 24, 2015

Does anyone know where I can find the GM bulletin that refers the truck tires to be road force balanced to 15 pounds or less?

Thank you. Is this actually a "legit" (for lack of a better word) GM-Chevy TSB that I can take to the dealer?

Well, the website is not a GM website and it's not a scanned image on an actual GM TSB, so can't say for sure if it is legit or not. The number of it (PI1354A) looks like a GM number but I haven't been able to find that TSB on any other site with GM TSBs. Not sure what to make of it.

Print it out, take it to your dealer, and if he says it's bogus, ask to see the actual "PI1354A" document. If he claims there is no "PI1354A", ask to see the index of TSBs. If they won;t show you, then draw your own conclusion.

FYI, I suspect it is legit, because the Shop Foreman at my delaership mentioned (on his own) that there is a bulletin to Roadforce to 15 lb. This is likely it.

Good luck.

Only way to fix the vibration issues is to trade your truck .

YUP! I dumped that vibrating 2014 Silverado and couldn't be happier. That truck was evil and was ruining my life with all it's problems. I hope everyoe is able to find satisfaction in the end.

I dont mean to be rude or anything, but unless you're trying to legit help someone don't comment like this. We know u taded your truck in and are happy now like 30 pages ago.

Agreeing with another forum member and also wishing everyone satisfaction in the end rubbed you the wrong way? I just popped in hoping to see people posting a viable fix for GM's vibration issue but ..nope. They're still selling 6000 lb vibrators with not a care on the world.

And $7/pound is a pretty hefty price to pay for one.

Mine vibrated today on the interstate, passengers seat was shaking. 1st time its done it since I put the Lt tires on, about 20,000 miles ago. I'm gonna go trade it for a ford.... NOT!!

You have a Ford my friend, I believe you're on the wrong site... Time to give it up...

For any Ford advocates,

I drive a 14' Ford XTR Extended cab as a work truck, and there's about 10 of them used as field trucks where I work in in Alberta. I can tell you first hand the problems Fords face even being the last year of the previous gen where there should be next to no bugs. Thing is, being pounded through the mud and dirt roads does it in on the suspensions and shocks, tire balancing, bearings,etc, but when you are having head problems (replaced), "VVT Phaser" issues, idler wheel bearing problems (20k km on a non field based truck), and the odd rough shifting of the transmission, off spec front diff resulting in complete replacement of the front end, and mysterious injector related issues resulting in the truck not being able to start, a transmission switch exposed to the debris of the road that can become jammed up with mud/dirt/snow/ice and you can't shift into gear. I enjoy driving my work truck, but it has it's quirks at 22k km (tranny switch problem)

Bear in mind these are work trucks that do take abuse (not so much on the engine/electrical side), there's a few items listed that shouldn't occur to trucks with less than 50k miles. I gander at both Ram and Ford forums as well, and even though I like Fords, the aluminum and the amount of electronic "everything" they piled into the truck just worries me too much for longevity. Ram by the looks of it has some serious electrical horror stories on brand new trucks with the BCMs requiring entire replacement, and the ecodiesel seems to be teething badly as well (http://www.dieselramforum.com/forum/new-member-introductions/5345-beware-new-eco-diesel.html few threads like this)

My personal 08 Sierra has been a tank that has taken abuse and put on a lot of miles in short time without many issues popping up. It vibrates going down the highway as well, even shaking water bottles, but it really doesn't bother me all too much (mind you the age of the truck).

I hope when I get my truck in roughly a month it doesn't vibrate or have transmission problems. All the ones I test drove including a friends seemed to be trouble free in all these "high problematic" areas except for the (now fixed) Sierra headlights. I am being cautious being a new vehicle because across most brands it does seem like quality control/assurance has gone by the wayside in favour of cost cutting.

How does ordering a new truck despite all the identified issues and "hoping that it does not vibrate or have transmission problems" qualify in any way as being cautious? To me it sounds like gambling.

If you want to be cautious, wait until GM proves that they have addressed and eliminated the known issues on these vehicles.

Years ago I too ignored complaints about problems with Volkswagen cars. I bought a new one hoping that it too would be perfect. It turned out to be the biggest lemon I have ever owned for a vehicle. So much for "hoping that mine will be trouble free".

Fair points. I guess I didn't mention I have been looking at gms for about a year now and waited for the 2nd MY to see what quirks and problems there might be. The other point I was trying to make with my stories about other brands of trucks was that purchasing any of them could be a gamble, which with 2014 fords should be the best bet being the last year of that Gen yet they still have issues.

I am excited for my truck to be delivered despite the issues, like I said I have been shopping for about a year now and I feel like I would equally be gambling if I looked at fords and rams. "Cautious" I suppose isn't a great statement for it, more like "playing the field".

Well, if they are putting new tires on it, insist that they do a proper Roadforce balance. Insist they Forcematch all 4 wheels and tires, and measure rim runouts first with the tires removed. Everything should be done using the stud adapter (not the centring cone). And, insist they do the "Centering" check that the Hunter machine can do first. And, insist they Roadforce balance to a maximum of 15 lb per the latest GM bulletin.

If they don't know what all that is, they they are not competent to do Roadforce balance. If they say it's not necessary, then they are not competent to do Roadforce balancing. If they don't give you the printouts after, to show they did it all, then they are not competent to do Roadforce balancing or are hiding something.

I'm not saying this will solve the vibration problem, but unless they do all that when they install new tires in an attempt to solve a vibration problem, they are wasting their time and yours. And, by the way, this is all pretty much covered in a GM bulletin some where. Doesn't mean every dealer follows it properly, but that is how it should be done.

Here's an update: I wasn't waiting for dealer to jerk me around anymore so I called GM myself and opened a claim. They tried co tacting the dealer several times, but dealer was avoiding them. Finally dealer made arrangements with GM to bring my truck back in Monday to look at suspension and rear differential. I've bern telling dealer things to look at based on this forum, but they keep saying "it's not that". GM keeps calling me asking me what I want and I tell them to fix it or buy it back so I can get a 2015. I keep stressing to them this is the 3rd time they're trying to fix...I'm trying to give the subtle hint of leMon law.

Any ideas on how to get GM to buy this back? They keep wanting to dump money into a sinking ship... i don't get it.

The best way is to research your states lemon law through the BBB site;

http://www.bbb.org/council/programs-services/dispute-handling-and-resolution/bbb-auto-line

GM will only have a certain amount of time once you've filed.
